SHUTTLE-BOX MOTION OF LOOM'SZ Specification of Letters Patent.

Patented'Oct. 15, 1907.

Application filed March 24, 1905. Serial No; 251,721.

invented certain new and useful Improvements in- Shuttle-Box Motions of Looms, of which the following i is a specification.

My invention relates 'to improvements in looms, and more particularly to improvements in the shuttle box motion of looms of the class which have two or more 5 shifting or change shuttle boxes at one, or both ends of the loom.

The object of my invention is to provide an improved construction of the connections, intermediate the pattern surface, which indicates for the movement of the shuttle box rod, and the shuttle boxes, and particularly moving through an arc of substantially one hundred and eighty degrees.

In my present improvements, I preferably locate the second crank in the connections intermediate the pattern indicator lever and the vertically moving shuttle boxrod, at the upper, part of the loom, and I provide a stand bolted to the loom side carrying a shaft and a rotary sleeve thereon; said sleeve having a crank" arm thereon and a gear which is adapted to, mesh with and be driven by a segment of a gear on an angle lever pivotally mounted on said stand, as will be hereinafter fully described.

I have only shown in the drawings sufiicient parts of a loom with my improvements combined therewith, to enable those skilled in the art to understand the construction and operation thereof.

Referring to the drawings :-Figure l is a rear View of one end of a loom frame, and parts of a loom thereon, showing two movable shuttle boxes, at said end with direction of arrow 11, Fig. 2. Fig. 2 is a section, on line 2, 2, Fig. 1, looking in the direction of arrow b, same fig.- ure; the pattern indicating mechanism is not shown. in this figure. Fig. 3 is a rear view of a loom frame, with parts of the loom thereon, showing four movable shuttle boxes at one end, with my improvements combined therewith. Fig. 4 is a section, on line 4, 4, Fig. 3, looking in the direction of arrow 0, same figure. The pattern indicating mechanism is not shown in this figure. Fig. 5 is, on an enlarged scale, an end view of some of the parts shown at the left in Fig. 4. The stand shownin Fig. 4 is not. SllOWIlllIl'lllllS' figure. Fig.6 is a ivertical section, on line 6, 6,, Fig. 5, looking in the directionof arrow d, same figure. Fig: 7 is a detached section, on line 7, 7', Fig. 4, looking in the direction of I arrow e, same figure.

In. the accompanying, drawings, 1 are the loom sides I or frames, 2 is a crank shaft, 3 the connectors-to the lay 4, carried on the lay swords 5, which. are pivotally mounted attheir lower ends on studs 6-.

On. one end of the loomat the upper part; thereof, in

this instance the right hand end, is-located the pattern mechanism for controlling the movement. of the shuttle boxes.

Said pattern'mechanism-may be of any ordinary. and well known construction, .in this-instance the well known Knowles type, shownand described. in U.

Reissue Letters Patent, No. 7 ,784,,of-.Iuly 3, 1877'. the construction of the connections shown and de- In the drawings IV have only shown the lower cylinder gear 7, the vibrator gear 8, .pivotally mounted on the vibrator lever 9, which is pivotally supported-at its outer end on. a rod 10, and. extendsover the pattern surface 11, carried onthe pattern cylinder 12,.and made up of rolls and-tubes, in the ordinary way.

I will now describamy improvements, andfirst. the improvements shown in Eigs.'. l and 2, inwhich. two

shuttle boxes .36 are. shown. at. one end of the loom;

A. stand 14, preferably made. of theshape shown in Fig. l, isbolted .to the upper part of the loom frame, at.

; the rear. partthereof, as shown in. Fig. 2. The stand 146 carries. a stud 15 on which ispivotallymounted. the hub 16 of. an anglellever 16. Onearmof the angle lever i 16 isconnecte'd at. one. end with. the vibrator. connector 17, and the other end of the vibrator connector 17 is pivotally connected with. the vibrator. gear 8-of the pati-- tern mechanism,.in the usual way. The other' arm. of the angle. lever 16 has thereon, at. its: outer-end, and 5 preferably integral therewith, teeth, or a segment of. i a gear 16 which. mesheswitha bevelgear 18', on a sleeve 19,, which. may be fast on a. shaft 20,,,rotative1y mountedin bearings 14 onuprightsl lf on the stand 14, or may be loose-onsaid shaft 20, to. rotate independs ently thereof.

my improvements combined therewith, looking in, the

The sleeve 19 has a. crank. arm 21. thereon, which has acrank pin 21.,.se.eured.in a slot in'said armby a bolt- 22, see Fig. 2.

On the crank pin 21 is-pivotall-y mount-- ed a hub 23 on the upper end of a'connector. 23. The

7, upper end of the connector 23 is; preferably bent. as shown in Fig. 2, to prevent the connector engaging with the stand 14. The lower end of the connector23is connected to one end of a box lever 24,- whieh is pivotally mounted on a stud 25. The stud 25is preferably carwardly extending arms 26 thereon, with bosses 26 at the outer ends of said arms having threaded openings therein, which receive the thumb screws 27, see Fig. 7.

The arms 26 have openings 26 therein, in each of which are supported and adapted to move in a horizontal plane, blocks 28, which are secured on the ends of a rod 29, on which are loosely mounted sheaves 30, around which the cords from the harness jacks, not shown, to the harnesses, pass.

The end of the box lever 24, opposite from the end connected to the lower end of the connector 23, carries a pin 31, on which is pivotally mounted the lower end of a give-way mechanism 32, which in this instance consists of two arms 32 and 32, which are pivotally connected at their lower ends, and yieldingly held together by a spring 33 at their upper ends, in the well known way. The inner edges of the arms 32 and 32 are recessed to receive a stud 34, in the usual way.

The stud 34 has a hub 34 thereon, see Fig. 1, through which the lower end of the box rod 35 extends, and which is held in the hub 34 by nuts 35 in the ordinary way. On the upper end of the box rod 35 are carried two shuttle boxes 36, shown in Figs. 1 and 2.

A balance spring 37 is preferably used in connection with the shuttle boxes 36, in the usual way; said spring 37 is attached at one end to a stud 38 on the loom frame, and at its other end to one end of a chain or flexible connection 39, passing over a pulley 40. The other end of the flexible connection 39 is attached to the stud 34. I

The operation of the shuttle box motion, shown in Figs. 1 and 2, at one end of the loom, will be readily understood by those skilled in the art. The movement of the vibrator gear or crank 8, from the position shown in Fig. 1, through an arc of substantially one hundred and eighty degrees, will, through vibrator connector 17 move the angle arm 16, and the segment of the gear 16 thereon, in the direction of the arrow Fig. l. The movement of the segment of the gear 16, in mesh with the bevel gear 18, will rotate said gear and the sleeve 19, and the crank arm 21, to cause said crank arm 21 to move to its opposite position, through an arc of substantially one hundred and eighty degrees. The movement of the crank arm 21 will, through connector 23, move'the box lever 24, and box rod 35, to change the position of the shuttle boxes, all as indicated by broken lines in Fig. 2.

In Figs. 3 and 4, I have shown my improvements in shuttle box motion connections, adapted to be applied to fourmovable shuttle boxes at each end of the loom.

In said Figs. 3 and 4, the connections shown in Figs. 1

and 2 are duplicated at each end of the loom, and two long vibrator connectors 17 extend back of the loom frame to the shuttle box motion connections on the opposite end of the loom.

The same letters of reference are used in Figs. 3 to 6 inclusive, for the parts similar to the parts shown in Figs. 1 and 2.

I will now describe the additional parts shown in Figs. 4 to 6, inclusive.

In order to obtain four different positions for the four different cells of the shuttle boxes shown in Fig. 4, I preferably use the form of compound box lever shown in Fig. 4. The main lever 41, Fig. 4, is centrally pivoted on a stud 42 on the casting 26, and on the forward end of said lever 41, on a stud 41, is pivoted a second lever 43, one end of which is connected to the lower end of the give-way mechanism of the shuttle box motion, and the other end is pivotally connected to the lower end of a connector 44. The upper end of the connector 44 is pivotally connected to a crank pin 45, secured in the slotted crank arm 46, see Fig. 6, by a bolt 47. The hub 46 of the crank arm 46 is fast on a shaft 20 which corresponds to the shaft 20, in Fig. 2, and is similarly mounted in bearings 14, on uprights 14 on the stand 14, see Fig. 3. On the inner end of the shaft 20 is fast a bevel gear 18, which meshes with a segment of a gear 16 on one arm of an angle lever 16, having a hub 16 piv- On the opposite end of the loom, or the end away from the box pattern mechanism, in case shifting shuttle boxes are used on said end of the loom, the same connections, intermediate the vertically moving box rod of the shuttle boxes and the vibrator gear, are used as above described, and the same figures of reference are used to indicate the same parts, shown in Fig. 3 of the drawings.

In order to operate the shuttle boxes on the end of the loom away from the pattern mechanism, so that the same pattern mechanism will operate both sets of shuttle boxes from one end of the loom, the vibrator connectors are lengthened, so that they will reach across the loom at the rear of the arch, as shown in Fig. 3.

In the operation of the loom, the movement of the pattern surface will move one of the vibrator levers to bring a vibrator gear into engagement with the upper or lower cylinder gear in the usual way, and the rotary motion of the vibrator gear will, through a vibrator connector and an angle lever connected therewith, and the segment gear on said angle lever, communicate a rotary motion to one of the gears 18, or 18, to operate oneof the cranks 21, or 46, and through a connector to the compound box lever, raise or lower the vertically moving box rod, and the boxes thereon, to the desired position relative to the race-way of the lay, according to the indications of the pattern surface, in the ordinary and well known way.

In each set of connections, intermediate the vibrator lever and the shuttle boxes in the 4 x 4 box loom are two cranks, each moving through an arc of substantially one hundred and eighty degrees, to obtain a double crank motion for moving the shuttle boxes.

It will be understood that the details of construction of my improvements will be readily understood by those skilled in the art.

The bracket, forming the support for the box lever,

and also the support for the guide sheaves, shown in the drawing, and above described, is not claimed herein, as the same forms the subject-matter of another application, Serial No. 366,111, a division of this aplication.

Having thus described my invention, What claim as new and desire to secure by Letters Patent is 1. In a shuttle box motion of a loom, a pivotally mounted box lever, connections therefrom to a crank, and said crank, a gear connected with and operating said crank, a pivoted lever having thereon teeth or a gear segment operating said gear, a connection from said lever to a sec- 0nd crank, and said second crank forming a part of the pattern mechanism.

2. In a shuttle box motion of a loom, the combination with a pivotally mounted box lever, and a vibrator lever, of intermediate connections, comprising therein a pivoted lever, having thereon teeth meshing with a gear, and said gear connected with and operating a crank, and said crank, and connections therefrom to the box lever.

3. In a shuttle box motion of a loom, a pivoted lever, having on one side thereof teeth adapted to mesh with and operate a gear and move a crank connected with said gear through an arc of substantially one hundred and eighty degrees and said gear and crank.

41. In a shuttle box motion of a loom, a stand bolted to the loom frame, a lever pivotally mounted on said stand, and having teeth thereon, and connected with the pattern indicating mechanism, and said pattern indicating mechan ism, and a shaft mounted on said stand, a gear on said shaft in mesh with the teeth on said lever, a crank on said shaft operated by said gear, and connections from said crank to the box lever, .and said box lever.
